getWidth

intersectAtPoint

Computes the 3D position (with elevation) and normal vector at the given
2D location in the terrain. The position is in scaled world coordinates
based on the given terrain scale. The returned data is encapsulated in a
IsectData3D instance.

toMesh

Creates a TriangleMesh instance of the terrain and constructs
side panels and a bottom plane to form a fully enclosed mesh volume, e.g.
suitable for CNC fabrication or 3D printing. The bottom plane will be
created at the given ground level (can also be negative) and the sides
are extended downward to that level too.
